Cop Claims Diddy Had Tupac Killed

A retired Los Angeles cop is convinced he’s cracked the case of Tupac Shakur’s decades-old murder — and the perp is none other than Sean (Diddy) Combs.

The music mogul formerly known as Puff Daddy offered Crips member Duane Keith (Keffe D) Davis $1 million to whack Shakur and his manager, Suge Knight, former LAPD detective Greg Kading boldly alleged in a documentary, according to the Huffington Post.

When the gang member’s nephew, Orlando (Baby Lane) Anderson, did the deed, he reportedly only got Shakur.

Kading, who once led a task force investigating the shooting deaths of Shakur and Smalls, supposedly wrangled a confession out of Keffe D after the Crips member feared facing charges for a different crime.

“If his intention was to just get away with it, so to speak, it would have been very easy for him to not include all the details that he did,” Kading told the Huffington Post.

Knight, 50, is currently serving jail time on charges he ran over two men with his truck, killing one, outside a Compton burger restaurant last January.

The documentary in which Kading makes his case — called “Murder Rap” and based on a book he wrote in 2011 — will stream on Netflix this spring.

A rep for Diddy has not yet replied to the Daily News’ request for comment.
